Bathroom renovations represent a significant investment in both comfort and property value. This guide examines the actual costs of bathroom renovation in Britain today – providing clear figures for different project scopes and explaining the factors that influence the final price.
Cost Overview
The cost of bathroom renovation varies substantially based on project scope:
| Type | Budget Range (£) | Typical Scope |
| Basic Refresh | £2,500-£5,000 | Like-for-like fixture replacement, limited tiling, basic suite |
| Standard Renovation | £5,000-£10,000 | New suite, partial layout changes, quality fixtures, comprehensive tiling |
| Premium Renovation | £10,000-£20,000+ | High-end fixtures, bespoke elements, potential structural changes |
These figures reflect full professional installation including materials and labour. The UK average for a standard bathroom renovation sits at approximately £7,000.
Costs by Bathroom Type
Cloakroom/WC Small cloakroom renovations with toilet and basin only typically range from £1,500-£4,000. Creating an entirely new downstairs toilet where none existed costs around £2,450 on average (£950 materials, £1,500 labour).
Standard Bathroom (3-piece) For an average family bathroom with toilet, basin and bath/shower:
- Small (2m × 2m): £4,000-£8,000
- Medium (3m × 3m): £5,000-£10,000
- Complete renovation with quality fixtures and full tiling: £7,000-£9,800
Master Bathroom/En-suite Larger bathrooms or those with premium specifications have higher costs:
- Standard master bathroom: £8,000-£12,000
- Luxury master with separate bath and shower: £14,000+
- High-specification large bathroom (4m × 4m): £12,000-£16,000+
The price difference between bathroom types reflects not just size but also the number of fixtures and typical quality expectations.
Material & Labour Breakdown
The cost divides between materials (40-60%) and labour (40-60%). Understanding typical component costs helps with budgeting:
Fixtures (supply only)
- Toilet: £120-£650 (standard close-coupled to wall-hung)
- Basin: £80-£800 (pedestal to vanity unit)
- Bath: £125-£1,500+ (standard acrylic to freestanding)
- Shower system: £100-£500+ (mixer to digital)
- Enclosure: £200-£1,000 (standard to frameless)
Installation Labour (typical)
- Toilet: £120-£350
- Basin: £100-£275
- Bath: £250-£400
- Shower: £250-£750
- Full bathroom removal: £500-£700
Materials & Finishes
- Wall tiles: £20-£100+ per m² (ceramic to natural stone)
- Floor tiles: £25-£120+ per m²
- Vinyl flooring: £10-£40 per m²
- Heated towel rail: £70-£600 + £200-£450 installation
- Underfloor heating: £40-£200 per m²
Tradesperson Day Rates
- Plumber: £250-£400 per day
- Electrician: £250-£400 per day
- Tiler: £200-£300 per day
- Bathroom fitter: £200-£280 per day
A complete bathroom renovation typically requires 5-10 working days for professional installation.
Key Cost Factors
Several elements significantly influence the final cost:
Layout Changes Keeping fixtures in their existing positions saves substantial money. Moving a toilet requires rerouting the soil stack (large diameter waste pipe), which adds complexity and cost. First-fix plumbing for significant layout changes can add £1,000-£3,000 to the project.
Quality & Specification Level The difference between basic and premium fixtures is substantial. A standard white toilet costs £120-£200, while a wall-hung model with concealed cistern costs £350-£800+. Similar variations exist across all fixtures and finishes.
Tiling Extent Full floor-to-ceiling tiling throughout costs significantly more than tiling only wet areas (around bath/shower). Tiling labour often costs as much as the tiles themselves (£100-£120 per m²). A typical bathroom might require 10-20m² of wall tiling and 3-5m² of floor tiling.
Plumbing & Electrical Requirements Modern bathrooms often require upgraded electrics for LED lighting, extractor fans, heated towel rails, or electric showers. Replacing outdated pipework also adds cost. Electrical work in bathrooms must meet stringent regulations, requiring qualified professionals.
Regional Variation Labour costs vary significantly across the UK:
- London/South East: 10-20% above national average
- Northern England/Midlands: Somewhat below average (5-10% less)
- Remote locations: Potentially higher due to travel costs
Professional vs DIY Installation
Professional Installation Using qualified tradespeople ensures proper installation, particularly for critical elements:
- Waterproofing/tanking (essential in wet areas)
- Plumbing connections (to prevent leaks)
- Electrical work (legally notifiable in bathrooms under Part P regulations)
- Structural modifications
A full professional bathroom installation typically takes 5-10 days and represents the safest approach for most homeowners.
DIY Options Some tasks can be handled by competent DIYers to reduce costs:
- Demolition/removal of old bathroom (saving £500-£700)
- Decoration/painting (saving £400-£700)
- Installing accessories and finishing items
- Managing waste disposal
Attempting plumbing or electrical work without proper qualifications risks safety issues and may invalidate insurance. A balanced approach often works best – DIY the appropriate elements while hiring professionals for technical aspects.
Practical Cost-Saving Approaches
Retain the Existing Layout Keeping fixtures in their current positions eliminates expensive plumbing modifications. This single decision can save £1,000-£3,000.
Shop Independently for Fixtures Purchasing your own fixtures and materials often saves money compared to using a bathroom company’s package. Compare prices across different suppliers and look for seasonal sales or ex-display items.
Mix Quality Levels Strategically Invest in quality for high-use items (taps, shower controls) and save on less critical elements. Use premium materials selectively for impact areas while choosing standard options elsewhere.
Limit Tiling Strategically Tile wet areas fully but consider half-height tiling or quality paint elsewhere. Large-format tiles can reduce labour costs as they cover more area with fewer grout lines.

Common Pitfalls
Inadequate Contingency Include 10-20% beyond your estimated costs for unexpected issues. Hidden problems (damp, rot, outdated plumbing) frequently emerge during bathroom renovations.
Overlooking Building Regulations Ensure compliance with ventilation requirements (extractor fans), electrical safety zones, and waterproofing standards. Non-compliance may require expensive remedial work.
False Economies Cutting corners on waterproofing, ventilation or preparation work creates significant risk of future problems. Invest appropriately in these foundational elements even if they’re not immediately visible.
Hiring Based Solely on Price Verify qualifications, insurance and previous work examples. Request detailed, itemised quotes to ensure fair comparisons. Quality workmanship prevents future issues.
Conclusion
A bathroom renovation represents a substantial but worthwhile investment in your property. By understanding the specific factors that influence costs and making informed decisions about where to invest and where to economise, you can achieve excellent results within your budget.
Setting realistic expectations from the outset and allowing for contingencies creates a solid foundation for your project. Whether undertaking a modest refresh or comprehensive transformation, clarity regarding costs enables confident decision-making throughout the renovation process.
